13 Claims. c1. 19-159 This invention relates to sliver coilers and moreparticularly to coilers using largecan's provided: with rollers or thelike to facilitate bodily movement of the cans and their contents fromone position to another.

It is customary to move sliver cans from place to place as a routineprocedure in textilemills; Frequently the cans are moved manually by anoperator who simply slides the cans along the floor in groups of fiveor. six cans. The trend toward cans of larger and larger diametersresults in substantial increases in the weight of the cans, particularlywhen filled with sliver. Thus with heavier cans to handle, it isbecoming more and more difiicult for an operator to move the cans about,especially where a particular operation requires him to slide a group ofseveral cans along the floor; In some instances it is necessary for theoperator to reduce the number of cans moved simultaneously in a groupand by so doing partially to defeat the purpose of using larger cans.

A principal object of this invention is to provide an improved coilerhaving a can mounted on rollers and having a platform arranged toreceive a'n'd' to position the can properly as Well as to hold the cansecurely in place while a coiling operation is effected.

Another object of this invention is the provision of an improvedplatform for sliver coilers wherein improved roller holding means arearranged to engage the can rollers and wherein improved guide means areutilized to engage the can rollers so as to guide the can into itsproper position on the-coiler platform. 7

The invention in one form comprises a coiler having a can with aplurality of rollers thereon and a platform having a plurality of rollerholding means together with a plurality of roller guide means arrangedto engage the can rollers and to guide them in to cooperative engagementwith the roller holding means on the platform.

The invention will be better understood from the following detaileddescription taken in conjunction with the accompanying drawings in whichFig. l is a side view of a coiler having a wheel mounted can; in whichFig. 2 is a plan view of a coiler platform constructed according to thisinvention; in which Fig. 3 is an enlarged view taken along the line 33of Fig. 2; and in which Fig. 4 is a plan view of a modification of theplatform shown in Fig. 2.

With reference to Fig. l the numeral 1 designates a coiler base on whicha pedestal 2 is securely affixed in conventional fashion. Mounted atopthe pedestal 2 is a coiler head generally designated by the numeral 3. Acan 4 is positioned on rotatable platform 5. As is well understood inthe art suitable mechanism is disposed within the pedestal 2 forimparting rotary motion to platform 5 and in addition to impart suitablemotion to a sliver fed into the top of the head 3 whereby the sliver iscoiled in a predetermined pattern within the can 4.

As can be seen in Fig. l the can 4 is provided with a plurality ofrollers 6; I V

According to this invention the rotatable platform 5 is contfucted wasto hold the roller mounted can 4 in position on the platform" and so asto enable an operator readily to position the can 4 in its propercentered re1ation on the rotatable platform 5. To this end and as bestshown in Fig. 2, the platform 5 is provided with a plurality of holdingmeans generally designated by the numeral 7. These holding means 7 mayconstitute an abrupt abutment 8 together with an inclined surface 9,-the abutment 8 and inclined surface 9 being shown enlarged in Fig. 3. ofthe invention it may be possible or desirable to eliminate the inclinedsurface 9 or the abutment 8 Also it is within the contemplation ofthepresent invention that the surface 9 and abutment 8 could take theform of a simple recess for receiving each can roller. As is indicatedby the arrow in Fig. 2 the direction of the rotation of the platform 5is clockwise. Thus the abutments 8 are disposed on the side of theholding means 7 which is opposite from the direction of rotation of therotatable platform 5. In this manner thexrollers of the can engage theabutment 8 and are securely held thereagainst as the can rotates againstthe frictional drag effect of the sliver being coiled. Inclined surfaces9 are disposed on the part of holding means 7 which is in the directionof rotation of the platform. Of course'the purpose of the inclinedsurfaces 9 is to allow the can to be gradually lowered from the mainportions 10 of the platform face into the holding means and intoengagement with abutments 8 and to impede rotation of can 4 in aclockwise direction relative to platform 5.

For the purpose ofguiding the rollers into proper engagement with theabutments 8 forming a part of the holding means 7, i.e. in order toproperly center the can 4 on the rotatable platform 5, guide means intheform of the outer guide elements 11 are provided. In addition, theinner guides 12 are also provided in spaced relation to the outer guideelements 11. Thus with the can positioned in approximately its correctposition on the platform 5 rotary motion is imparted to can 4manually'in a counter clockwise direction and causes each of the rollersto ride between one of the outer guides 11 and its associated innerguide 12 and thereby causes each roller toassurne its position withinone of the holding means 7.

In Fig. 2 the platform 5 is made up of an outer annular part 5A and aninner circular part 513 secured to the outer part by bolts 5C. Also inFig. 2 the inner guides 12 eX- tend only to the inner edge of annularpart 5A.

As is shown in Fig. 4 the platform 5 may be constructed of one piecesecured in place by bolts 5D and the inner guides 12A may extend intothe center SF of the platform 5 where they unite. By theconstruction ofFig. 4 the rollers are positively guided irrespective of the particularrelation between can 4 and platform 5 so long as one or more rollers isin engagement with the platform. The arrangement of Fig. 4 is thepresently preferred arrangement.

Preferably the rollers used in our invention are of the swivel typebecause such rollers are not subject to congestion by lint. As is bestshown in Fig. 3 each of these rollers comprises a rotatable wheel 13which is mounted on an axle 14 secured to a yoke member 15 comprising apair of spaced legs 15A and 15B and a bight portion 15C through which aswivel pin 16 extends. Pin 16 is anchored in a plate 17 affixedb'y'bolts' 18 and nuts 19' to a spider 20. Spider 20 preferably is inthe form of a triangle of unitary construction and is secured to the canby set screws 21 which engage the flange of can 4 to hold the swivelledrollers in place.

Can 4 is provided with a bottom 22 whose edge 22A is gripped between theflange ring 23 and the can wall 24. A reinforcing skirt 25 is mountedabout the lower edge of can wall 24 and the flange assembly is heldtogether by a plurality of units 26. The" manner of It will beunderstood that for some applications mounting the swivel rollers 6 tothe can is claimed in copending application Serial Number 747,232, filedJuly 8, 1958 and assigned to the assignee of this invention.
